This Omega was found in the bottom of a box while we were going through my fathers things and clearing out his house after his death. I have no details on it and no idea of its age or value. He did always admire accurate time pieces so that probably why he had kept this. Your knowledge and any information is greatly appreciated. I have been unable to find a likeness exactly like this, only ones with two or three stems instead of one.
That's a 15 minute sports stopwatch. It looks like an Omega MG 6306 with a cal 800 movement, first issued in 1966. These aren't greatly in demand so have limited value. It might be worth $50-150 depending on who is buying it, so it probably has more sentimental value as a keepsake. It's a nice little find.
Thanks so much for the information. We are planning on keeping the stopwatch as a keepsake, possibly to give to one of his grandsons sometime in the future.
